Hi. I have an A515-57 Aspire 5. It has some USB 3 type A ports and a Thunderbolt 4 USB c. One of the Type A ports has a small battery sign next to it (picture). I though it meant it was capable of high power delivery. I am charging my phone though, and I can barely get 5W out of it (picture). The laptop is plugged to the official acer charger, which is capable of delivering 90W, with not many app opens (mainly chrome), under the balanced power balance. My phone is capable of being charged up to 67W, and I am using the cable that came with the Xaomi 67W charger (this charger is capable of delivering 6,2A at 5V and 3,25A at 20V, so I know the cable can handle at least that much power). What is wrong? Also, do you know an app that shows what each USB port is capable of delivering in power and data, in an user-friendly way, instead of having to use Windows device manager?

    I think I might have found the answer. Although my phone can be charged at 67W, its USB port type is only 2.0. So I guess that when plugged to the Acer laptop it cannot use the full power delivery provided by USB 3. I don't understand how it can be charged so fast with the wall charger though. Any ideas on how to charge it faster from the laptop?
